2： Performance and advantages of food grade vacuum formed PET

Food grade vacuum formed PET (polycaprolactone) is a commonly used food packaging material. Its characteristics and advantages are:

High transparency: PET material has outstanding transparency, which can clearly display the appearance and quality of food.

High temperature resistance: PET material can withstand high temperatures and is suitable for packaging hot food.

Good physical properties: PET material has high strength and rigidity, which can effectively protect food from external pressure and compression.

Good chemical resistance: PET material has good resistance to chemicals such as acid and alkali, and does not react with food.

3： Food grade vacuum formed PET safety

Food grade vacuum formed PET is strictly controlled for food safety and meets relevant international and domestic standards, with high safety. Not emitting harmful substances, with no negative impact on food quality and health. In addition, PET material has a good barrier effect on oxygen, which can effectively protect the freshness and quality of food.

4： Characteristics and advantages of vacuum formed PP

Vacuum formed PP (polypropylene) is another commonly used food packaging material. Its characteristics and advantages are:

Good heat resistance: PP material can withstand high temperatures and is suitable for packaging hot food.

Good flexibility: PP material has better flexibility and stronger plasticity, and can be made into various shaped packaging containers.

Good chemical resistance: PP material has good resistance to chemicals such as acid and alkali, and does not react with food.

Environmental friendliness: PP material can be recycled to reduce adverse effects on the environment.

5： Blister PP safety

The vacuum formed PP has also passed strict food safety certification, meeting relevant standards and having high safety. Not emitting harmful substances, with no negative impact on food quality and health. However, it should be noted that PP material has strong flexibility and is prone to small scratches, pores, and the potential for bacterial growth. Therefore, it is important to maintain hygiene when using it.

6： How to choose suitable raw materials

The selection of food packaging materials should be comprehensively considered based on specific circumstances. Food grade vacuum formed PET can be used for packaging that requires high transparency and strength. For packaging that requires good heat resistance and flexibility, vacuum formed PP can be used. In addition, the cost of packaging materials, environmental friendliness, and recyclability should also be considered.

7： Draw a conclusion

Food grade vacuum formed PET and vacuum formed PP are commonly used food packaging materials with their own characteristics and advantages. When selecting, comprehensive factors such as food characteristics, packaging requirements, and safety should be considered. Regardless of the material used, it must be certified for food safety in order to ensure the quality and health of the food.
